NetCDF Format Support





Limitations/assumptions
Only WGS84 is supported
Only NetCDF following COARDS convention are
supported
ImageMosaic dimensions naming should be
consistent with that of the underlying NetCDF
reader
NetCDF output is available only for
StructuredGridCoverage2DReader implementors (
ImageMosaic and NetCDF)

WMS-EO
How this fits in
GeoServer’s world

GSIP 84

Wizard to configure EO
layer groups
Extending LayerGroup
concept
Support same style on
both raster and vector
data
Support custom
dimensions
Alter map on the fly to
support band
combination

WMS-EO

WMS-EO Quirks

Root layer must respond with a specific layer rather than the
composition of the children



E.g. when I send a GetMap for the root layer I could get back the browse image
default layer
Same styles for both Raster as well as Vector data


Kind of a default visualization for a certain Dataset
E.g. yellow can be use for both flags as well as outlines
Peculiar behavior for Band layer ( raw data )


Can request either 1 (grayscale image) or 3 (RGB image)


E.g. multiple bands at different wavelengths
Different combinations are prohibited
Peculiar Behavior for GetFeatureInfo

WMS-EO

Extending the LayerGroup GeoServer concept




Show the nested layers in the capabilities document
Allow the root of the group to be represented by a separate layer (the
overview one)
The above is a set of API, GUI and REST config changes, so a
GeoServer proposal is needed
Add the notion of custom dimensions in raster data





Needed to support the “eoproduct_bands” layer
Modify the GeoServer API to support custom dimensions (was almost
ready in this respect)
Modify the grid coverage readers API to allow new dimensions to be
exposed
Allow “dynamic” dimensions to be exposed (dimensions that are
configured by the user)
Adapt the GUI to allow new dimensions to be configured

WCS-EO

Build on top of a working WCS 2.0 with full extensions


CRS extension

Range subsetting extension

Interpolation extension

Scaling extension

GeoTiff extension


WCS 2.0
NetCDF extension
Add support for the WCS-EO extras

Listing coverage datasets in the capabilities documents (based on image
mosaic contents, which will have to be marked as “exposed” so that we
show their inner structure for EO)

Support describe coverage dataset

Support returning results for an entire dataset in GetCoverage

WCS-EO

Add support for downloading the original file in case of no
subsetting/reprojection/scaling/format change



Add support to GeoTools readers to signal they are returning us an
original file
Use that information to download the original file directly
Add support for WCS EO metadata in readers

Associate each file with EO metadata

Include such information in DescribeCoverage/DescribeEODataset
